To all whom it may concern:

Be it k11OWI1 l3l1at I, MAURIOE J. AoHoR, a citizen of the UnitedStates,v residing at Marion, in'the county of Grant and State ofIndiana, have invented certain new and useful Improvements in RotarySnow-Flows, of which the following is a specification, reference beinghad therein to the accompanying drawing.

The invention relates to-rotary snow plows and has for its object toprovide a snow plow that may be easily attached tothe front and end of arailway engine so that the same may be pushed-ahead of theengine and thesnowand ice removed fromthe track.

Conveying the snow and ice rearwardly over -a conveyer to ahopper,thence depositing the same-to either or both sides of-the track at anyangle desired.

A further object isto construct the plow so that it willtake the placeof the front truck, of the engine or tractor which furnishesits-propelling power and also the power for operating the variousmechanisms of the plow.

Afurther object'is to provide-a pivoted member, pivotally secured to themain frame of the plow, in which a rotary plow is carried and meanswhereby the pivoted member may be adjusted with relation to the roadbed.

A further object of the invention is to provide a snow plow, having apivoted member carrying a rotatable snow cutting member, meanshforrotating the snow cutting member and a rearwardly extending conveyerpivoted to the rotary snow cutting member" and so,constructed that thelower endof the rearwardly extending conveyer will remain initsrelativeposition to the rotary cutter when the pivoted-member isadjusted at various distances from the ground.

A further object bf the invention is to provide means whereby thenecessary power for operating the various mechanisms of the" ;membercomprislng arms 16 extendlng forsnow. plow will be furnishedxby thevehicle pushing the snow plowas a whole.

.A further object is to provide laterally disposed conVey-ers that maybe swung longiunder bridges.

With the above and other ob ects in. View which will appear as [thedescription proceeds, thei'nvention resides in the details of "theprecise embodiment of the invention herein described may be made withinthe scope of what is claimed without departing from the spirit of theinvention.

Figure 1 is a side elevation'of the plow, showing the same attached tothe front of a railway engine.

Fig. 2'is a top plan View of the plow showing the same detached from theengine.

Fig. 3 is a longitudinal vertical sectional viewthrough-the plow.

Fig. at is a sectional viewon line ll of Fig. 1.

Fig. 5 is an enlarged detail of a portion of the frame, showing theanechanism for operating the laterally extending conveyers.

Fig. '6 is a perspective view of rail scraper and ice cutter of thepivoted member.

Referring to the drawings, the numeral 1 designates a body frame andpivoted'to the front end thereof, by means of the bolt 3 is a truck 4.-of a conventional form. The truck 4 is provided with wheels5 adapted toengage and run on rails 6, how-everit is 'to be understood that wherethe plow is used on streets or roads and is being pushed by a tractor,that thetype of wheels may be varied. Secured to the end 6 of the bodyframe, by means of the bolt 7 is a rear truck 8 of a conventional-form,this truck is provided with wheels 9 similar to the wheels 5 of thefront truck and are adapted to rest upon the rails. The'upper end of thebolt 7 is pivotally mounted in a bearing 10, of the portion 11, of aconventional form of engine 12. It will be noted, that the front truckof the engine has been removed and the rear end 6 of the body frame ofthe snow ;plow substituted therefor, the rear truck 8 of the snow. plowservin as a front truck for the pushing or propelling vehicle.

Pivoted at '13, to the forward .end' of the bodyframe 1 isapi-votedmember 14, said the rotary druinQ-l. The drum 21 is providedwith spirally arranged cutter-Ibars2'2,

which'are securedto the surface o'f' the drum by means of the screws 23,so that they may be replaced with ease. Keyed to one of the pintles 20,by means of the key 24 is a crank arm 25. A pitman rod 26 has one of itsends pivotally secured'as at 27 to the crank arm 25, while its other endis pivotally secured as at 28 to a cross head 29, which is in turnguided in its 7 movement in the orosshead guide 30, said guide beingsecured to the side of the body frame-1 by means of the rivets 31. Apiston rod 32 is pivotally secured to the cross head 29 as at 33 and isreciprocated by means of the engine 34;, secured to the side of theframe 1 by the rivets 35. Steam is admitted to the engine through thesteam chest 36, pipe 37 and flexible steam hose 38, which is in turnconnected as at 39, to the steam supply pipe 40 leading fromthe engineto the steam chest 41. Valves 50 and 51 are provided controlling thesupply of steam to the engine 34:. It will be seen, that when the engine3 1 is in: operation, the rotary snow cutting drum will be revolved andits revoluble movement controlled the amount of steam supplied to theengine 34:.

A gear 52 is secured to one of the pintles 20 and meshes with a gear 53,rotatably mounted upon a stud 54 on one of the arms 15 and secured tosaid gear 53 and adapted to rotate therewith is a sprocket A. sprocketchain 57 extends around the sprocket 55 and sprocket 57 a which is keyedto the shaft 58, of the conveyer 59, said shaft 58 being rotatablymounted in bearings 60, of the arms 17. The conveyer 59 comprises sides60*, the lower ends of which are pivotally secured to the shaft 58,while its other end rests upon andslidably engages the snow hopper 60 asat 61, the purpose of which will presently appear. Rollers 62 aresecured to the shafts 58 and 63 and extending around said rollers andadapted to be rotated thereby is a conveyer belt 6i for conveying thesnow to the hopper 60 It will beseen that when the drum is rotated. thatthe snow will be thrown rearwardly on to the moving conveyer belt 64:which moves in the direction of the arrow at and that the snow will bedeposited in the hopper 60". Also it will be seen that ice plowed up bythe plow 18 will be forced backwardly upon the moving conveyer belt andthen deposited in the hopper.

The adjustmentof the pivoted member 14 in relation to the ground orsurface of the rails isaccomplished by means of jack screws 65, threadedinto lugs 66 integral with the body frame 1, their ends 67 engaging lugs68 integral with the pivoted member 14;. Thus it will be seen that whenthe jack screws are rotated, that the pivoted member. 14:, will beforced upwardly or allowed to assume a position closer to the ground. Ifthe cutters of the drum should hit an. 010. tru ti bl t, in h i thepivoted member will pivot upwardly and rise under its power, therebypreventing the breaking'of the cutters 0n the rotating drum.

The hopper 60 is provided with chutes 69, which discharge the snow toboth sides of-the machine and on to conveyers 70 and 71. Brackets 72support the hopper and maintain the same spaced from the body frame. Theconveyers 70 and 71 comprise sides 73 and are provided, at their ends,with rollers 7 a, mounted on and adapted to rotate with shafts '7 5 and76, extending around said shafts are belts 77, which move in thedirection of the arrows b, so that the snow will be discharged to thesides of the machine. Secured to the shafts 75 are sprockets 76, whichare rotated by means of sprocket chains 78, which in turn extend aroundsprockets 79 keyed to shafts 80 which rotate in the ends of theconveyers 7'0 and 71. U-shaped brackets 81, having upstanding. arms 82,supportinner ends of the conveyers and also have bearings 83 for theshafts 80. .Mounted in bearings 84 of the body frame l areverticalshafts 85,

said shafts forming a pivotal point for the brackets 81 and upon whichthe conveyers pivot when the conveyers are swung at dif ferent anglesrelative to the bodyv frame. Secured to the upper ends of the verticalshafts 85 are bevel gears 86, which mesh with bevel gears 87 which arekeyed to the shafts 80. Sprockets 88 are keyed to the vertical shafts 85and extending around said sprockets and the sprockets 89, keyed to avertical shaft 90, mounted in a bearing 91 of thebody frame 1 aresprocket chains 89*. Keyed to the upper end of the vertical shaft 90 isa crank arm 92 and pivoted to the end of the crank arm 92, as at 93 is apitman rod 94. The other end of the pitman rod is pivoted as at 95 to acrosshead 96, slidably mounted in a crosshead guide 97, said cross headbeing reciprocated vby means of a piston rod 98, operated by the engine99, which is secured to the body frame by means of the bolts 100, steambeing. admitted to the steam chest 101 of said engine through the branchpipe 102 and under control of the valve 103. I

It will be seen that when the crank arm is rotated in the direction ofthe arrow 0, that the conveyer belts will move in the direction of thearrow b and that the snow 1 bodyframe, without dis- 1 body frame 1, bymeans of the pins 104, which pass through apertures 105 in the brackets81 and through the apertures 106 in the body member 1. It will be seenthat the conveyers may be swung to the sides of the frame, when the pins104: are removed by means of the conveyer driving mechanism.
